PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit device, wherein the skewing of clock signal is reduced, while facility other than a semiconductor integrated circuit device is not required at all or does not produce any limitation with respect to a package. SOLUTION: For a semiconductor integrated circuit device comprising a plurality of internal circuits 4,... operating synchronously with a clock signal comprising a specified frequency are provided. A light-emitting element 2 for converting a clock signal supplied from the outside (from an electrical signal into optical pulse signal) and a plurality of photodetectors 3,... for generating electrical clock signal supplied to the internal circuits 4,... in accordance to the optical pulse signal from the light-emitting element 2 are provided on a semiconductor substrate, and the transfer of optical pulse signal from the light- emitting element 2 to the photodetectors 3,... is performed via a cover glass on a substrate surface. |
